Use 3-legged, “Login with Particle” OAuth to allow the end customer to set up IFTTT using the Particle channel, or

As a product creator you get your own IFTTT channel and use 2-legged auth with Particle white-labeled behind the scenes.

The feature @dave was talking about is not released or documented yet. We don’t want to circumvent IFTTT’s business model as they’re a valued partner, but if we can provide a way to use your own IFTTT channel with Particle’s servers so you don’t have to deploy and maintain your own server for IFTTT, we think product creators would find that super exciting and valuable.
